Study Notes
Developmental Anomalies of Teeth
Hutchinson's Teeth
- Characterized by notched or peg-shaped incisors
- Caused by congenital syphilis
- Teeth are smaller and more widely spaced than normal
- Often accompanied by other congenital defects
Dental Agenesis (Hypodontia)
- Failure of one or more teeth to develop
- Can be isolated or part of a larger syndrome (e.g. ectodermal dysplasias)
- Affects approximately 2-4% of the population
- More common in permanent teeth than primary teeth
Dens In Dente
- Also known as "dens invaginatus"
- Developmental anomaly of tooth development
- Characterized by enamel-lined invagination in the crown or root of the tooth
- Can be classified into three types based on severity
- Often associated with other developmental anomalies (e.g. taurodontism)
Dental Fusion
- Union of two or more teeth
- Can occur in primary or permanent teeth
- Classified into two types:
- True fusion: teeth are joined by dentin and enamel
- Fusion by concrescence: teeth are joined by cementum only
- Can cause spacing and alignment issues in the dental arch
Enamel Hypoplasia
- Defect in enamel formation
- Can be caused by genetic or environmental factors (e.g. nutritional deficiencies)
- Characterized by enamel that is thin, soft, or missing
- Can be localized to specific teeth or affect entire dentition
- Increases risk of tooth decay and sensitivity
